I'll play devil's advocate too. I "understand" why there are these rules. They are there for when people abuse things and then the association has something they can pull out and say, "uh-uh not allowed". It keeps home properties up, safety better, and provides an "understanding" of what's acceptable...
But, like most things that STARTED out as a good thing, they can be abused or misused. In my townhome association, we can't paint our trim of the house (the rest is brick) without getting permission on the color first, same goes for any outdoor changes - including changing house numbers, roofing, and patio/deck stuff. I know they are trying to prevent the situation of someone painting their trim neon orange, but to have to fill out a gazillion forms and waiting a few weeks just to paint my door a different shade - like from slate gray/blue to dark green, is overkill.
I understand the hanging the clothes out though. In some cultures, hanging clothes from any and all opening is the norm. Would you want to live next door (in a townhouse) to the family that has underwear and bras and socks hanging from the front windows on a string spanning one window to another? So, if they can't allow "that" they can't allow ANY laundry outside to be unbiased, so as a concession, I can't hang my sheets out in my fenced backyard.
I'm glad there are rules about what's allowed on property and lawn maintenance/landscaping is controlled because KIDS don't stay in their own yard and some people are just stupid and would leave dangerous things in their yard like an old fridge or freezer...
Where I think this "no business" rule came about was to discourage maybe some "dirty" business -literally and figuratively. Some businesses draw "critters" (I know, lived above an apt. where they would bring things in and out all the time - food? not sure) and we could NEVER keep the cockroaches away for long. All our neighbors said in our 3 flat and the one next door that the bug problem started when the "business" started.
And, would you want a tattoo artist next door that might bring in some unseemly clientele?
But, if people are reasonable, things can be worked around. I tend to be with the camp of, kill them with kindness, because if you cause a ruckus, they WILL find other things to nag you about.
